Abstract
A displacement sensor having a sensing body, a strain gauge, and a signal processing unit. The sensing body having a diaphragm positioned at a lower surface of the sensing body and an input bar orthogonally fixed at a center of an upper surface of the sensing body. The strain gauge attaches to the diaphragm. The signal processing unit generates an electrical signal based on an output value of the strain gauge corresponding to strain of the diaphragm caused by moment of the input bar.
